sii daynta mashruuca , kaas oo soo saara xirmo furan oo loogu talagalay in la geeyo qaybaha shabakadaha gacanta ee LTE/4G iyada oo aan lahayn qalab gaar ah, iyada oo la adeegsanayo kaliya qalab caalami ah oo la samayn karo, qaabka calaamadaha iyo habaynta kuwaas oo ay dejiyeen software (SDR, Software Defined Radio). Koodhka mashruuca shatiga ku haysta AGPLv3.
SrsLTE hirgelinta LTE UE (Qalabka Isticmaalaha, qaybaha macmiilka ee isku xidhka macmiilaha shabakadda LTE), saldhigga saldhigga LTE (eNodeB, E-UTRAN Node B), iyo sidoo kale walxaha shabakadda xudunta u ah LTE (MME - Hay'adda Maareynta Dhaqdhaqaaqa ee isdhexgalka oo leh saldhigyada aasaasiga ah, HSS - Adeegga Macmiilka Guriga ee kaydinta xogta macaamiisha iyo macluumaadka ku saabsan adeegyada la xidhiidha macaamiisha, SGW - Adeegga Kadinka habaynta iyo habaynta baakadaha saldhigyada, PGW - Xidhmada Xogta Shabakadda Shabakadda Gateway ee isku xidhka macmiilaha shabakadaha dibadda.
Nooca cusub:
- Taageerada tignoolajiyada helitaanka raadiyaha hore ee LTE MAC, RLC iyo lakabyada PDCP (Radio Cusub), oo loo sameeyay shabakadaha mobaylada ee 5G;
- Si loo fuliyo halbeegga (Internet-ka Narrowband of Things), oo loo isticmaalo in lagu xidho aaladaha Internet-ka is-maamulka ah iyo shabakadda mobaylada, koodka isku xidhka ayaa lagu daray;
- Taageero lagu daray algorithms-ka cryptographic , oo ku salaysan marin-biyoodka ZUC;
- srsENB (fulinta saldhigga saldhigga) hadda waxay taageertaa tignoolajiyada (Circuit Switched FallBack), kaas oo kuu ogolaanaya inaad dib ugu dhacdo 3G markaad samaynayso wicitaan cod ah haddii shabakadda LTE kaliya ay taageerto habka wareejinta xogta;
- Lakab ayaa lagu daray si loo socodsiiyo imtixaannada TTCN-3 si loo xaqiijiyo u hoggaansanaanta heerka qaybaha loo isticmaalo in lagu xidho macaamiisha shabakadda LTE;
- Qaab cusub oo lagu jili karo isgaarsiinta tareenada xawaaraha sare leh ayaa lagu daray jiliyaha kanaalka;
- Lakabyada RRC iyo NAS waa laga xoreeyay xannibaadda hababka hawlgalka.
Tilmaamaha muhiimka ah:
- Nidaamku wuxuu la shaqayn karaa transceivers kasta oo barnaamij ah oo ay taageerayaan Ettus UHD (Dareewalka Hardware ee Caalamiga ah) iyo darawalada bladeRF oo awood u leh inay ku shaqeeyaan 30.72 MHz bandwidth. Hawlgalka srsLTE waxa lagu tijaabiyay USRP B210, USRP B205mini, USRP X300, limeSDR iyo looxyada bladeRF;
- Codeeyaha la hagaajiyay ee xawaaraha sare leh iyadoo la adeegsanayo Intel SSE4.1/AVX2 tilmaamaha si loo gaaro in ka badan 100 Mbps waxqabadka qalabka badeecada. Hirgelinta caadiga ah ee codeeyaha ee luqadda C, siinta waxqabadka heerka 25 Mbit/s;
- Waafaqid buuxda oo la socota nooca 8 ee heerka LTE iyo taageerada qayb ka mid ah astaamaha nooca 9;
- Helitaanka qaabaynta hawlgalka ee habka qaybinta soo noqnoqda (FDD);
- Xajmiga la tijaabiyay: 1.4, 3, 5, 10, 15 iyo 20 MHz;
- Waxay taageertaa hababka gudbinta 1 (hal anteeno ah), 2 (gudbida kala duwanaanta), 3 (CCD) iyo 4 (isku-dhufashada boosaska xiran);
- Equalizer oo leh taageero loogu talagalay koodka soo noqnoqda ee ZF iyo MMSE;
- Taageerada abuuritaanka adeegyo loogu talagalay gudbinta nuxurka warbaahinta badan ee baahinta iyo qaababka badan;
- Awoodda lagu ilaalinayo diiwaannada faahfaahsan iyadoo la tixraacayo heerarka iyo qashinka qashinka;
- Nidaamka qabsashada heerka MAC, oo la jaan qaadaya falanqaynta shabakadda Wireshark;
- Helitaanka halbeegyo leh xogta raadraaca ee habka khadka taliska;
- Faylasha qaabeynta oo faahfaahsan;
- Hirgelinta LTE MAC, RLC, PDCP, RRC, NAS, S1AP iyo lakabyada GW.
